Great guide! now one question, does java programs need dependency or no? if they don't ill start java right away!

If you are talking about software dependency, yes you need both those softwares stated in OP.

If you are talking about other languages, you might need to learn C++, but you can start it with Java itself, its not that much based on any other language that you need to learn that first. But learning C++ will make it easy to understand variables, operators, other functions, but if you are fast learner, you can learn it easily without C++.
